Those are working fine for me. Which service pack of SW2015 you're using? Mine is SP 2.1
I just checked and mine is working fine. I'd be astonished if there is a setting that's causing the issue, but I suppose it's possible. I'd suggest un-installing SW, then re-installing to see if that works. If not, you might need to get your VAR involved.
My least favorite solution worked. I turned off the computer and turned it back on. Viola, full functionality. Thanks for the sanity check.
